Application filed November 24, 1906, Serial No. 344,844. Renewed June 22, 1908. BeriaiNo. 439,860.

To all whom it may concern:

Be it known that I, PETER MACA. Mao- KAsKIE, a citizen of the United States, and a resident of Central, in the county of Nye and State of Nevada, have invented a new and Improved Envelo of which the following is a full, clear, an( exact description.

'l he purpose of the invention is to provide an envelop with non-adhesive, auxiliary detachable llaps, adapted to be removed when the envelop is actually used for niailin purposes but which when in position on t e envelop will efectually prevent its sealing flap from becoming accidentally cemented to the body of the envelop whatever the climate and no matter what per cent. of moisture there may be in the atmosphere, and which will alsov prevent the accidental sealingl of the envelop even should it b'e dipped or dropped in water.

Another purpose of the invention is to provide an envelop constructed as described that may be formed from a single' blank, or wherein the auxiliary non-adhesive fla s may be attached to an envelop constructedD in the customary manner.

'lhe invention consists in the novel construction and combination of thc several parts, as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters o'f reference indicate corresponding parts in all the ligures.

Figure 1 is a back view of an envelop constructed in the improved manner, the sealing ilap being shown closed; Fig/2 is a view similar to that shoii'n in Fig. 1, the sealing flap however boingr shown raised and (lie auxiliary llaps as partly separated from libe body oi the envelop; Fig. Il is an enlarged sectional 'vieu' taken practically on the line oll ille blank troni which the envelop is made, drawn upon a smaller scale; and Fig. 5 is :t section similar to that shown in Fig. 3 but illustrating the auxiliary llap as attached to the body ol'- an envelop.

The envelop A can be made from a blank shown in li`ig.,4, herein the sind blank is body of the envelop and the sealing flap 11;

and said auxiliary flaps 15 referably extend beyond the outer edges of t e sealing flap 11 as is clearly shown in Fig. 1. These auxiliary fla s 15 are rendered non-adhesive by the app ication of oil, or they may be made of waxed papel' if so desired, the object of said auxiliary flaps being to prevent the sealing fla 11 from becoming accidental] cementei to the body of theenvelop in amp Weather or under clima ticconditions tending to that end. When the envelop is to be sent through the mail the flaps 15 are removed as is shown to the left in Fig. 2

While preferably the blank is made from one piece of material, it is evident that the auxiliary flaps 15 may be attached to an envelop of ordinary type by simpl y attaching them to the inner face of the back of the envelop and dividing the inner section of the 4auxiliary flap from the outer section by lines of perforations is shown in Fig. 5.

llaving thus described my invention, I

claim as new and desire to secure by Letters Patent,-

1. rllic combination with the body of an envelop and its-sealing flap, of auxiliary nonadliesive detachable lla is extending from the upper edge of the bot y below the sealing llap.

2. 'l`he combination with. the body of an envi-lop and its sealing llap, ol' auxiliary nonadliesive llaps extending l'roin the upper edge ol' the body below the sealing llap and projecting'tluiebeyond l'or preventing pi'emature adhesion ol the sealing lap,l said auxiliary llaps being partially separated from the body b a line ol' pei'loi'ations whereby to facilitate t ieir detachment.

ln testimony whereof I have signed my name to this specilication in the presence of given the elistoiiuiry formation, being pro-v two subscribing witnesses.

vided \\i1li a body 10, a closing llap 1l, side wings 12 and 113 and a bottoni etes-ing llap 14; but the blank dill'ersl'rom that ordinarily used in the construction of an envelop in that an auxiliary Vllap 15 is ina-Ie 1'ntegi'al riiijiiit ineittis'riiii ineKAsKiii.
